opp: Don't create an OPP table from dev_pm_opp_get_opp_table()
It has been found that some users (like cpufreq-dt and others on LKML) have abused the helper dev_pm_opp_get_opp_table() to create the OPP table instead of just finding it, which is the wrong thing to do. This routine was meant for OPP core's internal working and exposed the whole functionality by mistake. Change the scope of dev_pm_opp_get_opp_table() to only finding the table. The internal helpers _opp_get_opp_table*() are thus renamed to _add_opp_table*(), dev_pm_opp_get_opp_table_indexed() is removed (as we don't need the index field for finding the OPP table) and so the only user, genpd, is updated. Note that the prototype of _add_opp_table() was already left in opp.h by mistake when it was removed earlier and so we weren't required to add it now.
